I installed the latest Linux kernel (3.4.3). After rebooting, it says I am in Ubuntu 2D. How do I either go back to my previous kernel, or fix this problem? Thanks.
$ uname -r
3.4.3-030403-generic

This kernel apparently lacks drivers needed for Unity support, as it's a mainline kernel without Ubuntu added code and drivers.
To go back to your old kernel:
If you want to remove the non-working kernel, open a terminal and type
sudo apt-get remove linux-image-generic=3.4.3
